I need to know what gauge wire is on the fuseholder on a 51 Cub. I've tried searching it myself, but haven't seen it. It's time to do more on here, anyhow. It seems like usually I can find the answer to my question, or when somebody asks one of the very few things I do know, it's already been answered. I checked Owners, Operators, and Service Manuals. I find all manner of diagrams, but not the gauge. I'm starting to panic for time now with all the other things I have going, or need to get going on. I need a shortcut. Does anybody know right offhand where else to look, or knows what it is to help me cheat? Thanks, I appreciate the effort for a newb

Thank you both. This brings me to another question. I have a voltage regulator, and in dash fuseholder. Would I still use the same gauge wire as in this diagram? I ask this one only because I was sure the old, I thought original, fuseholder had two wires the same gauge. I can buy a copy of the one that was in there, but with the difference in price, I'm bound and determined to wire it myself, and learn something along the way. Also, I never heard of a cutout until I started reading here. Where can I read more about how it works? Is there some explanation in the service manuals? Is there something in the Cub B of K, or maybe somewhere else on the site? Thanks again!

You can purchase spools of multi-strand wire from any good hardware store as well as wire terminals. Building a wiring harness yourself will save you some money.

Cutout. I'm pretty sure there is an explanation on this site. For sure, if you search the internet there is an explanation. Basically, the cutout connects the generator to the battery when the generator voltage is higher than the battery voltage. When the battery voltage is higher than the generator output voltage, the cutout disconnects the battery from the generator.

That's all there is to it. The "regulating" is controlled by the operator of the tractor via the L(ow) H(igh) setting on the headlight switch.Don - that's a good schematic.
